Application

In the contemporary researches of massive constructive materials, aluminum and steel in first place, there is a trend of replacement of these two constructive metals with composite materials  so that the world science could be followed and to be given a contribution in extending the possibilities for manufacturing of more profitable processing in the composite industry.

From the previously published achievements and patents for advanced composite materials, a conclusion can be brought that the research, development and improvements of these materials are increasing and every day, new applications for them are being found. From the newest publications can be seen that there isn't a sphere of scientific areas, especially in the engineering, where the technology for advanced composites hasn't touched yet, and its application starts, in order to provide production of new high-performance materials for construction, building, electronics, aviation and rocket industry, in display applications, sensors, "intellectual" materials, etc... Or simply: the advanced composite materials slowly , but surely become constructive materials in the future! The material processing manner, so as the procedures that are used for production of composites, enables the constructor of the composites to have an open opportunity for producing material that will respond to the requirements for appropriate firmness and stiffness for a specific function.

In the last ten years, the composite materials have a great usage in the aviation, shipbuilding, automotive and other industries, trying to press out the aluminum alloys, steel and other materials. A lot of authors in their literature have given analysis for the application of the composites at global level and substitution of the conventional materials with composites. The development and application of composite materials with high stiffness, in the last years is of primary importance, also because of the special interest that exists for constructive metal substitution (aluminum and steel) with composite materials, providing construction alleviation and significant energy savings.

One comparative analysis of how much is the savings in material and energy by using the composite materials has been given through the following sample: There are data that in the aircraft structure, 20% of light carbon fiber composite is used, and that contributes for reduction of its mass by 30% which is quite significant, because with each tone of aircraft reduction mass, there is savings of 3000 tones of fuel in the airpcraft life-time. Today the weight percentage of light composite increases up to 50 in the airplane structure.

Another sample for the implementation of composite materials is for the production of wind turbines, so that the natural energy could be used better.
